    No. You can use differencing disks and create one parent image with
    all your software, etc, and then create child disks from that one

    Take a look at differencing disks in the VPC help for more details.

    I tried copying the vmc and vhd files, but the copies lose connectivity to
    the internet. The originals work fine, just the copies are bad

    If you're trying to run the copies the same time as the first VM, that wont
    work because the NIC address and machine name are the same.

    It's best to copy the VHD's, but create new .vmc files for each new copy,
    and then use something like Newsid to change the machine identifier the
    first time you run the VM. (You may not need this if there isn't a domain
    involved, but you should change the machine name.)

    I am only trying to run one at a time. I'm doing for version control and
    trying different sequences and combinations from a set point. I did try
    setting up a new vmc for each instance. Still no luck. Why would I need a new
    SID or computer name if each VC is run as a unique instance with no others

    You shouldn't.

    Can you open one of the .vmc in notepad and look for a line like this:

    ethernet_card_address type="bytes">0003FF0C0E1C</ethernet_card_address

    If it does, make sure the value isn't 0's and that it isn't the same as your
    host NIC.

    Are these vm's domain members?

    You might try static ip addresses in the VM...

  8. Keep in mind that duplicating Windows guests raises licensing issues.
